Hi everyone, I’m facing a strange and persistent issue with Windows Defender notifications, and I’m hoping someone here may have encountered something similar. During routine system maintenance, I noticed that Windows Defender has completely stopped showing notifications — no scan completion alerts, no threat‑found pop‑ups, nothing at all. Troubleshooting I’ve Already Done To rule out corruption, configuration issues, or hardware‑related causes, I’ve carried out extensive testing across multiple clean installations: Reinstalled Windows using the Media Creation Tool → still no Defender notifications Reinstalled Windows again using Rufus → same result Reset BIOS / cleared CMOS Installed an older Windows 11 build (offline, before updates) → still no notifications Deleted all partitions on every reinstall (full clean install) Verified all Windows Defender notification settings, including Enhanced Notifications Checked Windows notification settings to ensure Windows Security is allowed Ran SFC Performed DISM /Online /Cleanup-Image /RestoreHealth Confirmed no registry or Group Policy entries suppressing notifications Reinstalled Windows Defender components Scanned with third‑party tools and Microsoft MRT — no issues found Ensured Windows Push Notification System Service is running Despite all of this, Defender notifications never appear on any fresh installation. Microsoft Support I opened a support ticket with Microsoft. One engineer performed an in‑place repair install Another advised me to post the issue here for deeper investigation Ticket reference: 710148747 Additional Technical Findings 1. Notifications are not being suppressed No GPOs applied No Intune configuration profiles No registry entries modifying notification behaviour Local notification settings fully enabled Defender notifications fully enabled It’s not a profile corruption It’s not a user hive issue It’s not a local DB issue It’s OS‑level 2. Windows Notification Platform (WNP) appears to be the root cause Across multiple clean installs: ShellExperienceHost exists on disk. Focus Assist toggle produces no toast (not sure it does) other apps like mail, Logitech, steam can toast notification, i don't see defender toasting any scan notification. WNP is partially working Defender is partially registering The scan‑completion channel is failing specifically This behaviour is consistent and reproducible. 3. Defender functionality validated using EICAR I manually created the EICAR test file and ran a scan: Defender detects and removes the file correctly Detection appears in Protection History A threat notification appears Scan completion notifications do NOT appear This confirms: Defender itself is functioning The notification delivery layer (WNP) is not working question at MS QA- https://learn.microsoft.com/en-us/answers/questions/5864084/windows-defender-notifications-not-working-even-af71Views0likes1CommentError when Upgrading Windows from 23H2 to 25H2
Hi, I am really hoping that somebody can help me with the issue that I am experiencing right now which is as following: I work in school Environment, and I am trying to upgrade all the devices that we have in school at the moment to Windows version 25H2, but when I am doing that on devices that are connected to our school domain and still has Windows version 23H2 every time at the end of the process of upgrading the device it is undoing changes and getting back to Windows version 23H2. Can somebody help me with this problem? I have already use options such as: Windows Update from the settings, Windows Assistant from the official Microsoft Website, ISO image mounted on the computer and Media creation tool, but nothing has been successful so far. Every time it is undoing changes and getting back to Windows version 23H2. It would be great to have this issue resolved.

My HP laptop battery is stuck at 44% even when plugged in for over an hour. It shows charging, but the percentage doesn’t increase. When unplugged, the battery drains normally. This started after a recent Windows update. I’ve already tried restarting, reinstalling battery drivers, power reset, and checking BIOS settings, but nothing worked. Any solution for this?26Views0likes1CommentWindows 11 screen goes black after waking from sleep, only mouse moves
